It really depends if you are using some sort of a template engine.

1. If you're using plain PHP, the only option for you is to echo the variable:

   var current page = "";
   

2. Twig engine:

   var current page = "{{ your_var }}";
   

3. Smarty and RainTPL engines:

   var current page = "{$your_var}";
   

As you can see, there are other ways. All of them work fine. It really depends on how you'd like to write and organize your code. I personally use Twig and find it really easy,fast and straightforward.

Also, as others have pointed out, you can do AJAX calls to the server and fetch the variables like that. I find that method time-consuming, inefficient and insecure. If you choose this method, you will be posting requests to a script. Everybody will be able to do post/get requests to that script which opens your doors to some bots and DoS/DDoS attacks.
